Galaxy S7 Flat/Edge - During call on my Galaxy S7, receiving sound is not heard clearly with crackling and is broken irregularly. Also, volume is low. Why is this?
If receiving sound during call is not heard clearly or broken irregularly, firstly please check whether you attach Samsung-unapproved protector accessories covering perfectly all parts on Galaxy S7 device’s back.
Some of Samsung-unapproved protector accessories like films, covers, vinyl which attach on
device back side cover even Camera, Flash, HRM sensor and this causes to block the Air Path
inside the device.
Due to blocking of Air Path, receiving sound is not heard clearly or broken irregularly, and
volume may be also low.
Please keep in mind not to use Samsung-unapproved protector accessories covering Camera,
Flash, HRM sensor.
Also, use only Samsung-approved accessories. Using unapproved accessories may cause
the performance problems and malfunctions that are not covered by the warranty
